"Putin is the aggressor. Putin chose this war. And now he and his country will bear the consequences... that will impose severe cost on the Russian economy, both immediately and over time... The threat of the sanctions ... imposing the sanctions and seeing the effect of the sanctions are two different things. He's going to begin to see the effect of the sanctions. It's going to take time... We have to show resolve so he knows what is coming. And so the people of Russia know what he's brought on them. That's what this is all about.... Our forces are not and will not be engaged in the conflict... Our forces are not going to Europe to fight in Ukraine but defend our NATO allies and reassure those allies in the east... Putin's actions betray a sinister vision for the future of our world, one where nations take what they want by force...[the Russian president's actions would] end up costing Russia dearly, economically and strategically. ...I know this is hard and that Americans are already hurting... I'll do everything in my power to limit the pain the American people are feeling at the gas pump...[President Putin] has much larger ambitions than Ukraine. He wants to, in fact, reestablish the former Soviet Union. That's what this is about. I think that his ambitions are completely contrary to the place where the rest of the world has arrived."
